Field of the Invention The present invention relates to a static mixing element according to the preamble of claim 1 of the scope of the patent application. The present invention is also directed to a static mixer comprising such a mixing element. [Prior Art] A static mixing apparatus known from the prior art of the Chinese Patent No. CH 642 564, comprising a tubular housing and including at least one mixing element disposed therein . The mixing element includes a cross-bar that has an angle relative to the tube axis. The strips of the mixing elements are arranged in at least two groups. The strips within each group are substantially parallel aligned. A group of strips intersects a strip of another group. German Patent No. DE 44 2 8 8 1 3 shows a static mixing device which, in contrast to Chinese Patent No. CH 642 5 64, has a cross-over strip which overlaps in the region of the intersection. The partial widening of the strips which are produced as steel strips in German Patent No. DE 44 28 813 has the effect of a shape-fit connection for the reinforcement and/or for the formation of adjoining strips. A groove is cut into the widened portion which receives an adjacent strip of steel sheet material. European Patent No. EP 0 85 6 3 5 3 A1 shows a module which is provided as a component of a plastically flowable mixed product having a critical residence time. The device includes a tubular outer casing in which the straps are disposed. The strips are inclined relative to the longitudinal axis of the outer shell of the outer -5 - 200906480; they substantially intersect on a line perpendicular to the longitudinal axis. The module includes a sleeve that can be inserted into the housing. The static mixing device directs the inner wall of the hybrid product by the inner side of the sleeve. The strips are formed in the form of a mandrel, each mandrel having a top facing the direction of movement of the mixed product and a base secured to the inner side of the sleeve. Each top portion forms an intervening space relative to the interior wall of the device. The development of a mixer according to Chinese Patent No. C 4 6 2 5 6 4 in 1959 represents an improvement of an unexpected static mixing technique for a medium flowing in a laminar flow. This mixer has proven itself since then and has been successfully used in a wide range of applications with a large number of highly viscous media. We have been trying to improve this mixer for almost the next 30 years. However, despite substantial efforts and/or expenditures, only strong improvements can be documented. A modified mixer having a modified cross-section of the recessed strip is thus protected in U.S. Patent No. 6,467,949. For this modified static mixer, the independent rules f§ (M.Heniche, PATanguy, MFReeder 'J. B. F asano, January 2005 AlChE Journal No. 51, No. 1) It shows only a slight difference with respect to pressure loss and mixing efficiency. In another document recently published (S. Liu, PhD in McMaster University, 2005), the previous technique is modified in accordance with Chinese Patent No. CH 642 564 for the improvement of mixing efficiency and pressure drop. , using different technical inspections. Mixed components according to U.S. Patent No. 6, 4, 6, 7, 4, 9 B 1 are also measured in this document. With the same mixing effect' Liu recorded a 15% lower pressure -6- 200906480 loss, or a little worse pressure loss. By further variation in the cross-section of the strip, Liu additionally achieves a somewhat better mixing effect and has a pressure loss of up to 7.5 percent compared to the mixer according to Chinese Patent No. CH 642 5 64 . These examples of the improvement and inspection of the mixing behavior of static mixers having a similar structure to the mixer of Chinese Patent No. CH 642 5 64 show that the mixing efficiency of the laminar flow mixer has not been achieved today. There is no substantial improvement in pressure drop. Surprisingly, static mixer elements can be found to be unsuitable for use in the above statements, even if the contrary statement is correct. A clear reduction in the pressure loss observed using the mixing element according to the invention is a breakthrough in technology having a similar or improved mixing efficiency as recorded by the mixing element according to the invention. SUMMARY OF THE INVENTION The object of the present invention is to provide an improvement to the named static mixer, which can record a lower pressure loss and have a comparable or improved mixing efficiency. This object is met by static mixing elements as defined below. The static mixing element according to the invention has a width Db and is suitable for mounting in a hollow body having a width substantially equal to the width Db. The static mixing element includes a plurality of strip elements, and is provided with a first configuration comprising at least one first strip element, the first configuration being configured to be cross-sectionally equivalent to a second configuration comprising at least one second strip element. The first configuration and the second configuration include a different angle from the -7-200906480 with respect to the main direction of the flow. The first configuration and the second configuration include an angle greater than 0 degrees. In the protruding portion of the first configuration and the protruding portion of the second configuration, the intermediate space is disposed at least partially between the mutually adjacent strip members on a protruding portion plane, the protruding portion plane Set to be orthogonal to the main direction of the flow. The relative sum z of the widths of the strip elements measured in the direction of the width Db of the mixing element is less than 95 percent of the width of the mixing element. The further features relate to the static mixing element and to the invention according to the invention. An advantageous embodiment of a static mixer of mixing elements. The main direction of flow is preferably disposed in the direction of the longitudinal axis of the hollow body in which the mixing element is received. An intersection point is formed by the first configuration and the second configuration, and a spacer element can be disposed adjacent the intersection line. The spacer element can be formed as a partially thickened portion or a widened portion of at least one of the strip members. The number of the strip elements in the protruding portion plane can be a total of 4 to 10 pieces. Each configuration advantageously provides at least 2 strip elements. The first and third strip members are disposed in a portion of the first configuration of the strip elements in the first plane. The second and fourth strip members are disposed in a portion of the second configuration of the strip members in the second plane. At least some of the strip elements of the first configuration can be disposed in a third plane that is configured to be offset from the first plane. Alternatively or additionally, at least some of the strip elements of the second configuration can be disposed in a fourth plane such that the fourth plane is configured to be offset from the second plane. The strip elements have a width (H). Regarding the diameter (D) of the hollow body, the sum of the widths (H) of the strip members in the plane of the projection portion is 0.106480 degrees (Σ Hi) fixed by the parameter z defined hereinafter. The parameter z is particularly less than 95%, preferably less than 85%, especially less than 75%, particularly preferably less than 65%. The static mixing device includes a static mixing element and a hollow body or a sleeve to receive the static mixing element. The static mixing element can be fastened to the hollow body or to the sleeve such that the static mixing element and the hollow body or sleeve can be comprised of a single component. The static mixing element may be fastened to the inner wall of the hollow body in the region of the line of intersection of the first plane and the second plane, and/or in the region of at least some of the ends of the strip elements Or the inner wall of the sleeve. For media having laminar flow, particularly polymer melts or other highly viscous fluids, the preferred use of static mixing elements in accordance with one of the foregoing embodiments occurs. [Embodiment] Fig. 1 shows four mixing elements which are continuously disposed in a hollow body 1 . The continuous mixing elements 2 are pivoted about an angle of 90 degrees with respect to each other about the hollow body axis 8 serving as a rotating shaft. The main direction of the flow of the fluid passing through the hollow body 1 is disposed in the direction of the hollow body axis 8. Each mixing element comprises a configuration of strip elements (3, 4) which are arranged in two intersecting planes (5, 6). In this regard, the arrangement of the strip elements indicates a plurality of strip elements that are disposed substantially in a plane. The first plane 5 comprises a first configuration 2 1 of the strip elements 3; -9- 200906480 The second plane 6 comprises a second arrangement 31 of the strip elements 4. The first and second planes (5, 6) are disposed at an angle to each other such that the first configuration 21 of the strip members 3 intersects the second configuration 31 of the strip members 4. The adjacent strip elements are arranged to abut each other such that the sum of the widths (H) of the strip elements is equal to the tube diameter (D). In this case, the strip elements are therefore directly adjacent to one another. According to this embodiment, under the idealized assumption that the fluid molecules are flowing in the main direction of flow, 'each flowing fluid molecule impinges on a strip element. Each of the strip elements thus represents an obstacle to the fluid molecules of the flow such that the bias of the fluid molecules occurs before it impinges on the strip elements. This assumption is thus no longer applied to the interior of the static mixing element, a fluid molecule flowing in the direction of the main flow direction. The mixing of the fluid flow occurs by the bias of the fluid molecules from the main direction of flow. The resulting mixing effect will then improve with an increase in the direction from which the main direction of flow increases. However, the increased bias of fluid molecules from the main direction of flow generally represents an increased pressure loss. Since it is generally known, when a cross-section of a flow through is as unobstructed as possible, the pressure loss is reduced, and it appears that it is obvious to avoid the obstacle in the flow to reduce the pressure loss. However, after the same mixing distance, it will then be necessary to expect a less mixed mixing, because according to the previous opinion, the fluid element flows through the gap thus established without substantially biasing, ie substantially following the flow. Main direction, but not mixed with other fluid molecules. Surprisingly, the configuration of the strip elements according to Figure 2 can be found to be unsuitable for this statement. A static mixing element 2 for entering the hollow body 1 包括 according to the invention for installation -10 - 200906480 comprises a plurality of strip elements. The first strip element 3 and the third strip element 13 are arranged to intersect each other with respect to the second strip element 4 and the fourth strip element 14 . The first strip element 3 and the third strip element 丨3 form a first configuration 21 of the strip element. The second strip element 4 and the fourth strip element 14 form a second arrangement 31 of strip elements. The strip element can be designed, for example, as a tube or as a plate, disc, or strip. The cross-section of the strip element can be edgeless, for example having a circular or elliptical cross section. The cross section can include an edge, i.e., can have a rectangular or diamond shaped cross section. The connecting lines between the edges may be straight or curved, and may be particularly convex or concave, as realized in European Patent No. 1 3 0 5 1 0 8 Β 1. A strip element can project the associated configuration at least in a cross-sectional direction, such as having a wavy structure. In this case, the previously described plane of the configuration will be interpreted as a median plane. Furthermore, in a direction of arrangement, i.e. in the corresponding plane or parallel to the intermediate plane, the strip elements may also have an irregular structure, such as a wavy surface. In this case, the width 该 of the strip elements is defined as the width of the strip elements that are averaged over the length of the strip. The individual strip elements are also not required to extend parallel to one another in a configuration' but they may instead have an angle relative to other strip elements of the same configuration. The surprising effect of the present invention occurs in the cross-section of each of the strip members and in the shape of each of the strip elements; this is therefore largely independent of the cross-section and shape of the strip elements. If the two configurations 2 1 and 3 1 -11 - 200906480 protrude to a plane that is set orthogonal to the main direction of the flow, that is, the patriarch is about the longitudinal axis 8 ′ surrounding the hollow body 10 according to FIG. The strip elements of the configurations 21 and 31 are flush with respect to one another, i.e. there is no intervening space between the strip elements protruding in this way. In the comparison, if the same protruding portion is made in one of the specific embodiments in accordance with Figs. 2 to 4, the intermediate space of this type exists between the strip members. Figure 2 shows a radial section through the hollow body 1 , where the temple strips 3, 13 or the projections of the strip elements 4, 14 are accurately shown. In the representative figures, the strip elements have the width (Η) and the spacing (a) of each other such that the width (Η) and the spacing (a) of the adjacent strip elements according to this particularly preferred embodiment are equal. The surprising effect of the present invention also occurs when the pitches (a) and/or the widths (H) are different from each other. Figure 3 shows a second embodiment of a mixing element in accordance with the present invention. In this regard, when all of the strip elements of the configuration are disposed substantially in the same plane as shown in FIG. 3, or when all of the strip elements are disposed in substantially parallel planes as shown in FIG. In time, the plurality of strip elements form a configuration of the strip elements, however, the parallel planes are slightly offset in the direction of the longitudinal axis. A configuration of the strip elements consists of two or three strip elements in accordance with the embodiment of Figure 3. In this case, the first configuration 21 of the strip elements disposed in a plane 5 is comprised of the two strip elements 3, 13. The second arrangement 31 of the strip elements disposed in the plane 6 is comprised of the strip elements 4, 14, 24. The two intersecting planes 5, 6 are spanned by the first and second configurations. The first and second planes 5, 6 are disposed at an angle ' -12 - 200906480 such that the strip elements disposed in the first plane 5 intersect the strip elements of the second plane 6 and form a Intersecting line 7. According to Fig. 2, the following applies to the width (H) of the strip elements relative to the relative sum of the diameters of the hollow bodies: ζ = (^Ηΐ) / ΰ / = 1 if the widths of the strip elements are all the same , its application to z:

Preferably, the outermost strip element of the arrangement preferably contacts the inner wall surface of the hollow body or preferably has only a slight spacing from the inner wall surface. The diameter of the hollow body is specifically proposed for having round bezoar Hollow body of section. The hollow body can also have an elliptical, polygonal, in particular rectangular or square cross section. Instead of this diameter, a width measurement Db is then used for z and applied to the following relationship: ^ N-\ D b = ^ Hi or if the width of the strip elements and each of the equally spaced lines are the same , -13- 200906480

As above, this hereinafter is equally applied to z: z = N*H/Db accordingly. The width Db of the hollow body substantially corresponds to the width of the mixing element, while neglecting manufacturing and assembly tolerances. According to the invention 'in any case 2 < 95%, preferably z < 85 percent, especially z < 75 percent, particularly preferably z < 65 percent. Meanwhile, according to the present invention, in each case, the sum of the surfaces of the strip members which are vertically protruded to the two intersecting arrangement elements on a plane also amounts to less than 95% of the total cross-sectional area of the plane. Preferably, it is less than 85 percent of the total plane, especially less than 75 percent of the total plane, and particularly preferably less than 6 5 percent of the total plane. The number N of strip elements is preferably a minimum of 4 and a maximum of 1 値. Production tolerances or mounting tolerances are usually not considered in this formula. If the strip elements do not contact the inner wall of the hollow body, the mounting and removal of the plurality of fully prefabricated mixing elements can be performed more simply. Any and all of the thermal expansion of the mixing element can occur largely unimpeded during operation. Depending on the flow medium and the structural design of the mixing element, the dead zones can be formed in the marginal regions if the strip elements are directly connected to the inner wall of the hollow body. For this reason, it is also possible to provide a small spacing between the inner wall surface of the hollow body and at least some of the strip elements, as in the European patent EP 0 8 5 6 3 5 3 Presented in A No. 1. Further specific embodiments are shown in FIG. Different from FIG. 3, all of the strip elements (3, 13, 23) of the first configuration 21 are not disposed in a plane 5, but instead some of the strip elements are disposed in a plane 5' 'the plane 5 'The system is substantially parallel, but at least slightly displaced in the direction of the longitudinal axis. In a broad study, the geometric parameters of the static mixing element are systematically varied and the mixing is evaluated relative to pressure loss and mixing efficiency. The nature of the result of the device. Static mixers of different lengths are caused to be compared to each other with respect to pressure loss, and the pressure loss per length of the mixer is calculated in the optimization. The quality of mixing in a plane A is described by the coefficient of varying CoV. It is defined as the standard deviation of the concentration distribution in A and is normalized to the average 値 of the concentration ^ in A.

Comparison of different mixers The reduction in the coefficient of the varying CoV is determined over a predetermined mixer length having the same distribution, and thus also has the same CoV before the mixers; there is a smaller according to the predetermined length The mixer of CoV is therefore more strongly or preferably mixed. -15 - 200906480 The results of this study show that the mixing elements have significantly more advantageous properties with a spacing (a) between the intersecting strip elements. The spacing (a) is preferably about the same amount as the width (H) of the strip members. Pressure losses having the same throughput and the same flow cross section can be substantially reduced relative to the prior art and have the same and/or improved mixing qualities after a predetermined length. It is possible to reduce the pressure loss by 2/3, and have the same mixing quality or even better. Pressure loss versus relative to the length of each mixer after a predetermined mixer length of the mixing elements in different embodiments of the invention, in accordance with the prior art of Chinese Patent No. CH 642 5 64 For the quality of the mixer, the results of this study are shown in Figure 5. In this regard, the pressure loss is input to the abscissa relative to the pressure loss of the prior art, and the mixing quality after a predetermined mixer length is input relative to the blending quality of the prior art after the same mixer length. On the ordinate. The individual point 1 9 corresponds to a pair of pairs for relative pressure loss and mixing quality in accordance with the prior art. In the representative figure, the pair is normalized to (1, 1); the relative pressure loss according to the present invention is thus between 20 and 80 percent of the pressure loss according to the prior art. After a predetermined mixer length, the CoV is between 75 and 125 percent of the prior art. The shape of the curve 20 is so clearly shown that even a significant improvement in the quality of the mixing, especially between 75 and 100 percent CoV can be recorded, despite this substantially lower pressure loss. At this point, it is necessary here to again note that a smaller CoV as defined above represents a better blending quality. With a suitable design of -16-200906480, this relative pressure loss can be reduced by more than two-thirds of the pressure loss of the prior art. In other variants, the mixing quality after a predetermined mixer length can be improved by up to 20 percent relative to the prior art according to Chinese Patent No. CH 642 564, while reducing the pressure loss over According to the Chinese patent c h 6 4 2 5 6 4 mixer can record 50%. In this illustration, the mixing element shown in Fig. 3 corresponds to a point having a pressure loss of less than about 60% less than the prior art, and has a better mixing of 20% after the same mixer length. quality. According to the embodiment of Figures 3 and 4, the spacer elements (15, 16) are arranged at least partially between adjacent strip elements. It may be possible to install the connector elements or to simplify them by means of such spacer elements. Moreover, the spacer elements can be used to increase the stability of the static mixing element. In this regard, the spacer element can be a separate component that can be attached to the strip element by, for example, soldering, or can be formed in the form of a partially thickened portion or a widened portion. An example for such a widened profile is shown in Figure 6 in the region of the strip element adjacent the wall. Figure 6 shows the detail of the intersection of the two strip members 3, 4 having spacer elements 15 and 16 in the form of partially thickened portions and widened portions. Suitable thickened portions have the function of connecting the two strip members to each other. The thickened portions are substantially limited by the intersection area. Since the thickened portion 6 represents only a partial connection of the strip elements, it has at most a small effect on the flow. -17- 200906480 BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described hereinafter with reference to the drawings. 1 is a static mixing device according to the prior art; FIG. 2 is a view of a static mixing element according to the first embodiment of the present invention; FIG. 3 is a static mixing according to a second embodiment of the present invention.
